T o all whom it may concern.'

Be it known that we, BERNARD A. FULLER and MILES BATEMAN, each a citizenof the United States ofAmerica, and resident of Centerville, Appanoosecounty, Iowa, have invented a new and useful Concrete-Block Mold, ofwhich the following is a specification.

The object of this invention is to provide improved means for moldingconcrete blocks.

A 'further object of this invention is to provide improved means forsupporting pallets of various thicknesses.

A further object of this invention is to provide improved means forinterchangeably mounting mold plates.

A further object of this invention is to pro vide improved means forinterchangeably making solid or hollow blocks.

A further object of this invention is to provide improved means foradjusting one or both end plates of the mold to make fractional blocks.

A further obj ect of this invention is to provide improved means fordetachably connecting the various mold members during the operation ofmolding.

Our invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in our claims andillustrated by the accompanying drawing, in which- Figure 1 is a plan ofthe complete machine in position for molding and adjusted for makinghollow blocks. Fig. 2 is a front elevation of the same machine, thecores removed. Fig. 3 is an end elevation of the same machine in thesame position. Fig. 4 is an elevation of a pallet-carrying frame.employed therein. Fig. 5 is a perspective of a plate employed at timesto iill a core-opening in a mold plate, and Fig. 6 is a longitudinalsection of a mold plate and two of the filling plates in positiontherein. Fig. 7 is a detail section illustrating the adjustment of themachine for making fractional blocks. Figs. 8 and 9 are end elevationsof concrete blocks made in this mold.

In the construction ofthe machine or mold as shown, the numeral 10designates legs connected in pairs by end bars 11, .each end bar formedwith a large notch 12 in its upper margin and near one end, the pairs oflegs connected by front bar 13 and rear bar 14 at right angles to theend bars. Ears 15, one of which is shown in Fig. 3, are formed onlscrews 38 in the sockets.

bars l1. A rectangular face frame 16 is formed with ears 17 extendingrearward in line with its end portions and parallel with the ears 15. Ahinge-pin or rod 18 is mounted through and pivotally connects the ears15, 17, thus hinging the face-frame to the end bars. Sockets 19, one ofwhich is shown in Fig. 7, are formed on the inner faces of the ends ofthe face-frame 16 and a face-plate 2() is provided with lugs 21 adaptedto be inserted in said sockets and secured therein removably andreplaceably by set-screws 22 mounted in the frame and engaging the lugs.The face-plate 2O may be of any desired face, or configuration, andvarious forms of such plate, of the same general size, may be employedinterchangeably on the frame 16. A pallet frame 23 is formed with ears24 eX- tending in alinement with its ends and pivoted on the hinge-pinor rod 1S. The palletframe 23 is formed with webs 25 in its cornerportions and set-screws 26 are screwed through said webs and engage therear face of a pallet 27. The pallet 27 may be of any desired generalthickness and material, such as a two-inch plank or a thin metal plate,and the set-screws are employed to adjust said pallet to the end-platesofthe mold hereinafter described irrespective of the thickness of thepallet. The pallet-frame 23 also is formed with ears 28 arranged inpairs on and projecting longitudinally from each end thereof and saidears are apertured to receive split keys 29 or other pivot pins.

Ears 3() are formed in pairs, and spaced apart materially in the pairs,and project outwardly from the ends of the face-frame, and yoke-bars 31,32 are pivoted to said ears by means of hinge-pins or rods 33, 34. EX-tremities of the arms of the yoke-bars 31, 32 extend beyond thehinge-pins 33, 34 andare adapted to engage the ends of the faceframe attimes and limit oscillation of said bars. End-plates 35, 36 are formedwith sockets 37 projecting outwardly from their central portions andsaid sockets are adapted to receive the upper portions of the yokebars31, 32 and be secured thereto by set Each yoke-bar 31, 32 is formed witha boss 39 below its center and apertured for the reception of a bar 40adjustable longitudinally therein and secured by set screws 41 in thebosses. The bar 40 carries an arm 42 at right angles to itsand rise fromthe central portions of the end i in the socket 37 at times and hold theend plate at a distance from the yoke-bar (Fig. 7) in the making offractional blocks. Ears y43 areformed on and project forward from thefront of the face-frame 16 and a yoke-frame 44 is formed with ears 45arranged parallel with the -ears 43 and pivoted thereto by a hinge-pinor rod 46. A core-plate 47 is provided and is formed with sockets 48,48a adapted to receive arms of the yoke-frame 44 and be secured theretoby set-screws 49 in said sockets engaging said arms. The coreplate 47 isformed with handles 50, 50, projecting forward from its upper portion,and also is formed with core-openings 51, 51 adapted to admit cores 52,52 removably and replaceably. The end plates and core plate may be ofany desired face or configuration and different plates of the samegeneral size may be used interchangeably therewith. It is believed to belpreferable to make the end plates and core plate with inwardlyprojecting central portions or ribs 53 that will produce grooves 54 inthe ends and grooves 55 in the bottom of a block 56, as shown in Fig. 8,in order that a wall built of such blocks may have vertical andhorizontal air spaces and mortar locks; but the pallet 27 also may beprovided with such rib on its face to produce a groove 57 in a blocksuch as 58 as shown in Fig. 9, thus materially increasing the horizontalair spaces in a wall. A iilling plate 59 formed with a lip 60 (Fig. 5)may be mounted in each of the core openings 51 and be secured therein byturn-buttons 61 on the core-plate 47 (Fig. 6) when it is desired todispense with the cores 52 and mold solid blocks in the machine. Ears 62are arranged in pairs and project longitudinally from the upper portionsof the ends of the core-plate 47 and locking bars 63, 64 are fulcrumedon the split keys 29, or other pivots employed in lieu thereof, andengage at times in said pairs of ears. The rear end portions of thelocking bars 63, 64 extend rearward of the fulcrums core-plate rigidlytogether and hold the mold in stable condition during the operation ofmolding.

In practical use the parts are assembled as .shown in Figs. 2 and 3;concrete is tamped into the mold to a plane above the lower margins ofthe core openings 51 and is screeded flush therewith; the cores 52 areinserted through said openings and bedded slightly; concrete is tampedin the mold on each side of and above the cores until the mold is full;the concrete is screeded flush with the top of the mold; the handles 50are grasped and the mold turned manually to the rear on the axis of therod 18 until it rests on the bar 14 and legs connected thereby, thedeposit of the mold being cushioned by impact with a spring on said rearbar; the cores are withdrawn through the core plate; the wheelnuts 65are loosened from the ears 62 and the locking bars 63 64 are movedlaterally from said ears; the end plates are moved away from the ends ofthe block; the core plate 47 is moved forward until the ears 45 of theyoke-frame -44 contact with the faceframe and then the core-plate,yoke-frame, face-frame, face-plate and end plates are moved forward awayfrom the block. The pallet 27 is then lifted from the pallet frame 23and carries the block to a place of deposit on said allet for curi'ng.The parts are then reassem led with another pallet in the recumbentposition on the rear of the supporting frame; the mold is repositionedas shown in Figs. 2 and 3 and the operation of molding is repeated.

Fractional blocks are made, either with or without cores according tolength of block, and character required, by the same operation, the endplates or either of them being adjusted as shown in Fig. 7.
